ANSWER ANY OF THEM AND ILL BE GRATEFUL THANK YOU !!!!!!!Arnold and Jeremy are working on a rocket project for math class. Their job is to find the time it takes for a model rocket to reach its maximum height and how long it will take the rocket to return to Earth if the rocket’s parachute fails to deploy. They are making calculations for three different rocket engines and each engine has a different initial velocity. They are a bit confused on how to make the calculations. Take a look at the information that they were given and show them how to set up the equations and solve for the times requested. ````````````````````````````````````````````````````````````````````````` 1. A model rocket is launched from the ground with an initial velocity of 160 ft/sec. a. How long will it take the rocket to reach its maximum height?

To make a glass sphere, 113.04 cm^3 of molten glass is poured into a mold. Using 3.14 for π, Wen finds the circumference of the sphere using the steps below. V=4/3πr^3 113.04=4/3(3.14)r^3 36=4/3r^3 r^3=27 r=9 C=2πr C=18π C=56.52 cm Which statement about Wen’s calculations is true? A. Wen incorrectly calculated the radius. B. Wen did not use the correct formula for the circumference. C. Wen should have used the length of the diameter to find the circumference. D. Wen should have used another formula for the volume.

Khianna is looking for a geocache in an amusement park. The geocache is located inside the park’s puppet theater.This map shows the location of the geocache and the route Khianna will take to reach it:The map scale is 500:1. This means that distances in the park are 500 times as far as they are on the map.1. First, Khianna must walk from the front gate to the Ferris wheel. This distance is 2.5 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ___________2. Then, she must walk from the Ferris wheel to the fountain. This distance is 5 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ____________3. Next, she must walk from the fountain to the refreshment stand. This distance is 2 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ____________4. Then, she must walk from the refreshment stand to the go-cart track. This distance is 1.5 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ____________5. Then, she must walk from the go-cart track to the swinging boat. This distance is 4 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ____________6. Then, she must walk from the swinging boat to the merry-go-round. This distance is 3 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters) Show your calculations below. ____________7. Then, she must walk from the merry-go-round to the puppet theater. This distance is 5 cm on Khianna’s map. How far is the actual distance in the park? (Give your answer in meters.) Show your calculations below. ____________8. What was the total distance that Khianna had to walk, from the front gate to the puppet theater? (Give your answer in meters.) Show your calculations below. _____________9. When she arrives at the puppet theater, she must search the entire area for the geocache. On the map, the drawing of the puppet theater is 1.5 cm long and 0.5 cm wide. What is the area of the actual puppet theater? (Give your answer in square meters.) Show your calculations below. _____________PLEASE HELP I WILL MARK BRAINLIEST
